It doesn't seem intuitive to me. No, I do not have any examples; partly because I am speculating instead of comparing implementations. However, an RTF can be optimized for addition, while a node-set must allow fast traversal and direct (XPath-addressed) access. Many RTFs are not used as node-sets, thus this should make sense. I know from experience that switching tree model in Saxon 6 changes performance pattern. Instead of (or additionally to) having two tree structures, it would make sense to use different tree structures for node-sets and RTFs.
